- A 2% increase in upfront costs towards supporting sustainable building design has been reported to result in a life cycle savings of 20% of the total construction costs. So a $100,000 investment on a $5 Million project would result in a savings of $1 Million over the life of the building.
- Buildings are the single greatest opportunity to reducing carbon dioxide emissions, contributing to 40% of the world's carbon dioxide.
- Electrical and mechanical systems are responsible for more than 50% of a buildings annual energy costs.
- Recycled materials can dramatically reduce energy consumptions. Aluminum can be recycled for 10-20% of the energy used to transform raw ore into finished aluminum. Key recyclable building materials: Glass, Plastics, Brick, Wood and Metals.
- If every home in the United States replaced their five most used lights with energy efficient lighting or fixtures, the energy costs savings would be close to $8 Billion every year while preventing the greenhouse gas emission of nearly 10 Million cars.
- 80% of the dirt entering a building comes from occupant’s footwear, read “Walk Off Mats” section to learn more.
- Paints, stains and other architectural coatings emit 9% of the Volatile Organic Compounds from consumer and commercial products, being the second highest after automobiles.

- The United States could save nearly 640 Billion gallons of water per year by replacing old, inefficient toilet models with EPA WaterSense labeled toilets.
- Air leaks from a poor building seal account for 25% to 40% of the energy used for heating and cooling, thus, having an airtight building seal can offer significant cost savings for a home or building.
- Solar heating for pools can offer a return on investment as low as two years while extending the swimming season by several weeks.
- Buildings account for 68% of United States’ total electricity consumption and 38% of the total carbon dioxide emissions.
- Buildings use 40% (3 billion tons annually) of the world’s raw materials.
- It is estimated that of the 209.7 million tons of municipal solid waste generated in the U.S. in a single year, 136 million tons of it is generated from building related construction and demolition.
